Derivation of transport equations for a strongly interacting Lagrangian in powers of $\hslash$ and $1/N_c$

S. P. Klevansky, A. Ogura, J. Hüfner

Transport theory for an interacting fermionic system is reviewed and applied to the chiral Lagrangian of the Nambu-Jona-Lasinio model. Two expansions must be applied: an expansion…
